The strange thing is I don't actually play the game. I only use it as a method of enabled Episode Metal. Also, personal tastes and OCD if you ask.
Would it be possible to encrypt APKs to ASECs manually or through a script? For example, Sonic 4 Episode I is listed as "incompatible" in the Play Store and I sideloaded the APK from my dad's phone. It looks awfully awkward to have it sticking out in my /data/app folder rather along with my other paid purchases (Sonic 4 Episode II) in /data/apk-asec and /mnt/asec.
